# A spectral-Galerkin turbulent channel flow solver for large-scale simulations

@article{Mortensen2017AST, title={A spectral-Galerkin turbulent channel flow solver for large-scale simulations}, author={Mikael Mortensen}, journal={ArXiv}, year={2017}, volume={abs/1701.03787} }

A fully (pseudo-)spectral solver for direct numerical simulations of large-scale turbulent channel flows is described. The solver utilizes the Chebyshev base functions suggested by J. Shen [SIAM J. Sci. Comput., 16, 1, 1995], that lead to stable and robust numerical schemes, even at very large scale. New and fast algorithms for the direct solution of the linear systems are devised, and algorithms and matrices for all required scalar products and transforms are provided. We validate the solver…
